1. Boot the Desktop/Live CD. (Use Ubuntu 8.04 or later)
2. Open a terminal (Applications -> Accessories -> Terminal)
3. Start grub as root with the following command :
sudo grub
4. You will get a grub prompt (see below) which we will use to find the root partition and install grub to the MBR (hd0,0)
[ Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists the possible completions of a device/filename. ] grub>
Type the following and press enter:find /boot/grub/stage1
If you get "Error 15: File not found", try the following:find /grub/stage1
Using this information, set the root device (fill in X,Y with whatever the find command returned):grub> root (hdX,Y)
Install Grub:grub> setup (hd0)
Exit Grub:grub> quit
5. Reboot (to hard drive). Grub should be installed and both Ubuntu and Windows should have been automatically detected.
